描述 Description

AZC299-02S is a design which includes ESD

rated diode arrays to protect high speed data

interfaces. The AZC299-02S has been

specifically designed to protect sensitive

components which are connected to data and

transmission lines from over-voltage caused by

Electrostatic Discharging (ESD).

AZC299-02S is a unique design which includes

ESD rated, low capacitance steering diodes and

a unique design of clamping cell which is an

equivalent TVS diode in a single package. During

transient conditions, the steering diodes direct

the transient to either the power supply line or to

ground line. The internal unique design of

clamping cell prevents over-voltage on the power

line, protecting any downstream components.

Besides, there is a back-drive protection design

in AZC299-02S for power-down mode operation.

AZC299-02S may be used to meet the ESD

immunity requirements of IEC 61000-4-2, Level 4

(±15kV air, ±8kV contact discharge).
